Color-scheme proposal
[edit]Note
[edit]- The original proposal (see below) has been simplified as described in
{{Minor planet color code legend}}
, which is as of 2016, not only used to color the section headings in {{Infobox planet}}, but also used to color the background in the partial minor planet lists. - The currently most obvious discrepancy is the background color for main-belt asteroids in {{Infobox planet}}, which still needs to changed from to a generic grey such as
- The original discussion from September 2015, can be found on WT:AST (archive).
Description
[edit]The templates {{Infobox planet}} and {{Infobox comet}} are used in about 3,500 articles on wikipedia (see number of transclusions for infobox planet and infobox comet). Both templates have a parameter that allows to set a background-color for the subheadings (either optional or hard-coded). This is a proposal for a color-scheme applied to these subheadings that corresponds to an object's classification. It's a simple 3-step classification, which neither claims to do justice to more intrinsic cases nor demands the template "infobox planet" to be changed. It's rather harmless and purely optional. I'm also prepared to make the actual changes myself.

- Rationale for amended colors
- MBA's account for 97.5% of all minor planets (presumably also the largest segment among the MP-object articles by far). To use a generic "grey"-background color in {{Infobox planet}} seem most appropriate and will then also loosely correspond to the coloring used in the partial list. A grey color was previously intended for all the randomly colored articles about "Satellites". But this has not been implemented, so there is no conflict in re-assigning a new color (which has not been decided yet).
- NEOs a Mars-crossers (MCA) had a too similar color, so that is could not be easily distinguished (screen-color configurations do vary alot indeed). MP-object articles of MCA still use the older color-version, while partial LoMP tables have been colored with the revised version.
- Currently all infoboxes in the TNO-segment receive the same color. A distinction between KBOs, SDOs and DDOs is due to their small article number not very helpful (as of 2016, there are only 332 numbered TNOs out of a total of 1⁄2 million numbered MPs). However this may change in the future.
- A distinction for inner, middle and outer MBAs will not be made for the bg-color in {{Infobox planet}}. Instead a generic "grey" will be used (as described above).
- Hexcodes for above colors are:
#FFC2E0 | NEOs | #FA8072 | MCs |
#FEFEFE | MBA (inner) | #E9E9E9 | MBA (middle) |
#D6D6D6 | MBA (outer) | #C2FFFF | JTs |
#C7FF8F | Centaurs | #C2E0FF | TNOs |
Comments
[edit]- ^ includes candidates, limit to be defined
- ^ literally anything that is found (permanently/most of the time) at or within Neptune's orbit
- ^ the comparably few near-Earth comets (NECs) are not included since they are already assigned to the basic category for comets
- ^ any type of trojan: Earth trojan, Mars trojans, Jupiter trojans, Neptune trojans?
Rules
[edit]§1 | Basic categories overrule everything else:
|
§2 | The remaining objects are divided into TNOs and CNOs. Default colors are used if no appropriate subdivision is available (which is identical to the color of a subdivision; so TNO=KBO and CNO=main-belt). This simplifies things: the color-scheme is a simple thing and not meant for special and rare cases. |
§3 | There is no third rule |
Implementation
[edit]Custom colors used in articles
[edit]A number of articles have their individually given color. These include:
Moons
[edit]- Mars: Deimos (moon) and Phobos (moon)
- Moons of Jupiter (67): Callirrhoe (moon), Iocaste (moon), Io (moon), Ganymede (moon), Europa (moon), Callisto (moon), Dia (moon), Elara (moon), Lysithea (moon), Leda (moon), Themisto (moon), S/2003 J 12, S/2011 J 1, Jupiter LII, Ananke (moon), Carme (moon), S/2011 J 2, Jupiter LI, Pasiphae (moon), Sinope (moon) and S/2003 J 2
- The moons of Saturn have no color (or no template) except for: Fenrir (moon), Ymir (moon), Ijiraq (moon), Pan (moon), Daphnis (moon), and Phoebe (moon)
- No colors for the moons of Pluto (5), the moons of Haumea (2), the 27 moons of Uranus, and the 14 moons of Neptune.
- Minor-planet moon: Romulus (moon), Remus (moon), Petit-Prince (moon), Linus (moon)
- TNO-moons – colors: Vanth (moon), no colors: Hiʻiaka, Namaka, Dysnomia

Optional colors
[edit]Potentially useful color to disamig current scheme (e.g. Trojans of Neptune that are currently receive centaurs/TNOs colors rather arbitrary)

Unclassified minor planets as per current JPL-derived taxonomy
|background=
#B88A00

Detached objects - ie. extended SDOs, extended scattered disc objects E-SDOs, scattered–extended, distant detached objects (DDO)
